Disc 19 has a hollow hub 19"}titted on hub 18. As clearly shown in Fig ure (5. the discs l8'19 haveradial, lint arms .ll:3"---l9 quarter turn twisted and ham 1 ing: ontheir extremities hemispherical buckets 18"19 The buckets are all synmetrically disposed and those oi one disc are interposed between thoseoi? the othe' disc.

An object of my present improvement is to obtain the impact of the fullcroswsectionh opposite sides 01' the cup edge are huge 3:2

ot' a stream of water projected into the shell tangentially to thebucket series and an object is to throw the impinging: \vater rentrallyand reduce the amount deflected laterally so that side wall clearancemay be reduccd without increasing dead water re sistance.

To that objective, I provide hemispheri- 'al buckets which are laterallyoll'set as to the plane of their disc and which discs havep theirbuckets o'l'l set in a direction opposite, to that oi. the other. Inother words the right-hand disc has its bucket series oli'set totheright'of its plane and the left hand disc has its bucket series contrawise. liach bucket has an inner side portion extr-unlinp; across theplane of the dis .1 a distance eutlicientto intercept the wholecross-section of the stream of impelling water projected in a linetangent to the center or pitch line on the bucket series (note Figure6). The concave faces of the buckets are presented to the stream andinstead of the water oi the stream being split and thrown laterally inreversion of flightand crowding against the side of walls and chokingthe impeller it is diverted by the palm ot the bucket inwardly orcentrally, thus quickly clearing the bucket impacted. The buckets aresuccessively staggered.

The rotor has practically no side play and is therefore noiseless.

The nipple 7 contains a water-nozzle which is coaxial with the nipple (iwhich forms the outlet side of the motoix The water-nozzle consists of ahollow plug" or casing 22 baring u countersunk gaskct 23 tightly butturnably fitting the bushing ll. The plug is grooved peripherally at Ato receive a key screw E25 holding it only against axial movement. ()1:the inuer end oi the plug, is a centrally orilired end wall 26 and inthis is a needle valve 2? whose threaded shank 28 passes out through theouter end of the plup bodv and has a thumb head 29 by which the screwmay be turned to-change the volume of lien past lillfl the motor bodilyon the axis needle valve to permit oil the use motor shaft as needed, atdifferent from vertical to horizontal while attached to the faucet.

the needle 27 and thereby the power and speed of the turbine wheel, andwater consumption.

It is desirable to enable the motor to be applied readily to faucets andwater outlets o'li various shapes and sizes, and also provide for bodilyswinging the motor orbitally around the faucet end as may he desired,and further, to provide for swing;

oi the of the angles l herelore, the plug), or valve oily 22 has alaterally opening cup 22 ontaining a thick, double concave \VtSllGl' 0having a rather small port av bl. On

ind these pass into and interlock in an finternally slotted adapter ring33 telescopng; over the cup and seating on the gasket It The adapter maybe slipped up around he laucet mouth and secured firmly. Quickdctacluuent oi the motor from the mounted tdupter may be accomplished bymerely swinging;- the motor around the faucet until the lug iii aredisengaged from the channelled ring :lastened to the faucet. To attachthe adapter to the faucets oil various SIMON set screws 35 are disposedradially in the ring and these may be screwed in to firmly attach theadapter in a position in which the gasket is lirmly jammed up againstthe faucet mouth. I

ll hen the water is turned on it backs up in the needle valve casing orplug and since the area of the lower side of the gasket pre sented towater pressure is greater than the area at the mouth of the faucet itwill be seen that the gasket is bowed up against the lip of the faucetand leak prevented.

Any suitable means may be employed to fasten the motor body in differentangular adjustments while its supporting plug is attached to the faucet.In the present case the plug has a small counter-sunk, resilient latchinter-hooked in a recess 38 and having an outwardly springing dog-end39, (Fig. ill) snapping into the notches 11 in the motor bushing 11.Figure elshows the latch 37 pressed in to release the motor bod so thatit may be turned on the plug 252 to another desired position.

An object of the invention is to provide a method for making the turbinewheel. By my method a blank disc B of suitable nniterial as brass, isfirst cut, then this is stamped to-form the arms as '19" with thebuckets l9 and to punch out the shaft hole and form lugs 19 (or cutapertures 18 in disc 18 when this the piece being formed). Either withor subsequent lb these operations the hub ol the disc is drawn and thebuckets are also drawn. \Vhen the drawing steps have been completed, thepiece is trimmed. After the trimming is finished the piece is subjectedto action of means whereby the buckets are turned from the plane of thedisc to an angle of 90 degrees thereto and at the same time the bucketsare given the desired lateral offset from the plane of thedisc. Then adisc 19 with lugs 19 is, laid against a disc 18 and the lugs 19 areclinched down after being passed through the perforations 18.

The above method produces a turbine wheel which cannot be made as a.casting with any degree of economy, if at all.

The invention claimed is; 1

1. A device of the class described, having a shell with anintake'nipple, a mounting plug on which the nipple is rotativelyournaled, means connecting the nipple and the plug against end movement,and a positive latching device mounted on one of said parts andoperative to lock them relatively at predetermined positions.

2. In a device of the class described, a mounting ring for attachment toa faucet spout and having set screws to fix it in place, the bore of thering having a circular groove with lateral entrances in the near end. ofthe ring, and a bearing member, for

a motor shell, having a part turnably lit in the ring and havingexternal lugs to 1nter-' lock in the said groove and permit readyattachment and detachment of the bearing member to and from the ring bya partial turn of the member without removing the ring from the faucet.

3. In a motor of the class described, a

mounting ring for attachment to a faucet spout and means for fixing itin place thereon, said ring having an interrupted internal bore-surfacegroove, a bearing member to turnably fit in the ring bore and havingexternal lugs to interengage in the said groove to detachably connectand disconnect the parts by a partial turn, and a gasket in the top endof said part and which is compressible against the rim of the mouth ofthe faucet when the bearing member is interengaged With the ring.

4. A device of the class described, having a shell with an intakenipple, a mounting plug extending into and on which the nipple isrotatively journaled, means to prevent end movement of the shell. on theplug, and a latch in the plug for locking the shell against rotation.

5. A device of the class described, including a motor shell for a Wheeland having an inlet nipple tangent to the wheel, and a mounting elementengaging the nipple and connectible with a conduit outlet, and having avalve to vary flow to the wheel.

6. A device of the class described, including a motor shell for a wheeland having an inlet nipple tangent to the wheel, and a mounting elementengaging the nipple and connectible with a conduit outlet, and having avalve to vary flow to the wheel;'said element having a lateral gasketcup and a gasket therein to am against the end of the conduit outlet;
